Letters Patent No. 100,295, dated March 1, 1870.

IMPROVEMENT IN CARRIAGE-TOPS.

The Schedule referred to in these Letters Patent and making of the same.

To all whom it may concern:

- Be it known that 1, Moses T. JACKSON, of Montrose, in the county of Susquehanna, and State of Pennsylvania, have invented a new and useful Im? provement in Garriage-Topsyand I do hereby declare. that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to.

'ment of the spring and its mode of connection with the brace and prop, whereby it is adapted for adj ustment, as and for the purpose hereinafter set forth.

A represents the rail that runs around the seat of the carriage. To the rail A, at or near its rear corners on the seat of the carriagcfare rigidly attached, or upon it are formed outwardly-projecting arms B, to the outer vends of which the lower ends of the jointed or bracearms 0 are secured by a nut, in the ordinary manner.

D is a wire spring coiled around the arm B, and the inner end of which is secured to the inner end of the arm B, or to the rail A, or to the seat, by being passed through an eye attached to the one or the other of said parts, or by other convenient means.

The other or outer end of the springD is secured to the lower part of the jointed arm 0 by being in- 'serted in a hole or socket formed in said arm, as shown in fig. 2.

The coiled spring Dis arranged insuch a way that when the carriage-top is being lowered and when lowered its weight will be partially supported by thetensiou or elasticity of the said spring, so that 'it cannot only be raised and lowered easily, but when lowered its weight may be partially supported by said springs, making it ride easily and preventing the bows from being broken by the weight of said top.

When by long use increased weight of thetop from havingbecome wet ormuddy during a storm, or from other causes, the spring fails to properly support the same, the spring may be readily shortened, so as to increase its power by drawing 'its ends, respectively,

through the hole in the brace and lug, and then securing them as before.

The prop or arm B is cast in one piece with the rail A, and hence cannot rotate. Under a modified arrangement the prop might be removably connected with the rail, but in no case so as to rotate. Y

I am aware of the patent granted to J. L. Alien, January 14, 1851, but I desire to be understood as claiming nothing therein shown or described.

Having thus described my invention,

I claim as new and desire to secure by Letters Patent- The spring D, arranged on the fixed outwardly-projecting arm B of the rail A, and having its ends secured in the holes in the brace and lug, respectively,

so as to be adjustable as and for the purpose specified.

' M. 'l. JACKSON.
